Aircraft Hangar | Heavy-Duty Steel Structures for Large & Military Fleets

A storage hangar keeps weather off the wings. A large aircraft hangar keeps a B747, a C-17, or a tactical fleet operational through conditions that would shut down a standard building.

We engineer heavy-duty steel aircraft hangars as hybrid portal-frame and space-truss systems in Q355B high-strength steel. That combination delivers 60 m to 180 m of column-free clear span with clear heights starting at 15 m—enough for tail stands, overhead cranes, and full wing-tip clearance on wide-body jets. Every frame is calculated for your actual location: wind gusts, seismic zone, snow drift, and soil bearing. Not catalog engineering. Site-specific engineering.

The structure is protected with coatings rated against jet fuel, de-icing fluid, and salt-air exposure. Door systems, MEP galleries, and crane rails are integrated at the design stage—not retrofitted after the slab is poured. When the building has to perform under load, you cannot afford to discover a gap in the spec sheet.

Door & Access Systems

Aircraft-Scale Access, Not Industrial Doors Scaled Up

The door is the most stressed component of any metal airplane hangar. We size and engineer the door system to your fleet profile:

• 200-ton self-balancing sliding doors for the largest commercial and military openings
• Bi-fold hydraulic doors for full-height openings without ground-track interference
• Stacking multi-leaf doors for very wide bays where lateral space is limited

All door frames are integrated into the primary steel structure during design—not added as an afterthought. Wind bracing, weather sealing, and thermal breaks are calculated as part of the frame system.

Corrosion & Environmental Protection

Aviation-Grade Coating Systems

Jet fuel, de-icing fluid, and salt air will destroy standard industrial coatings. Our steel aircraft hangar structures receive:

• Hot-dip galvanization (80–120 µm) on all primary steel components
• Multi-coat anti-corrosion paint systems for exposed surfaces
• Chemical-resistant topcoats rated against aviation fuels and glycol-based de-icers

In coastal or tropical environments, we specify enhanced coating systems with extended salt-spray resistance. The target is a structural service life exceeding 30 years with minimal recoating.

Hybrid Structural System

Portal Frame + Space Truss Hybrid

The primary frame pairs rigid welded portal frames with a space-truss roof system. The portal frames carry vertical and lateral loads down to the foundation. The space truss distributes roof loads across the full span without introducing interior columns.

Columns and rafters are welded H-sections in Q355B steel (ASTM A572 Gr 50 equivalent). Connections are high-strength bolted for field assembly with minimal on-site welding. The hybrid approach gives you the stiffness of a rigid frame where you need it—at the columns—and the span efficiency of a truss where you need it—across the roof.

Clear Span & Interior Height

Column-Free Spans from 60 m to 180 m

Interior columns are not an option when you are maneuvering an A380 or parking multiple tactical aircraft in a single bay. Our large aircraft hangar designs eliminate interior columns across the full span. That means:

• Full wing-tip clearance for wide-body jets
• Unobstructed crane coverage across the entire floor plate
• Tail-stand access and maintenance platform positioning without structural interference

Clear height scales from 15 m upward to match your tail clearance and crane hook height requirements.

Engineered Load Ratings

Designed for the Location, Not the Average

We do not design for “standard” conditions. We design for your location’s actual environmental loads:

Load Type	Rating	Application
Wind	Category 17 typhoon-equivalent sustained gusts	Coastal and exposed airfields
Seismic	Zone 9 compliance with ductile frame behavior	High-seismic regions
Snow	2.0 kN/m² with drift and unbalanced loading	Northern and alpine sites
Floor Load	Reinforced slab rated for aircraft jacking and engine hoists	MRO and heavy maintenance bays

Integrated MEP & Utility Systems

Built-In Infrastructure, Not Retrofit

Large hangars are not empty shells. They are working buildings with complex utility demands:

• Roof MEP galleries pre-embedded for fuel lines, high-voltage power, and fiber-optic data cables
• Photovoltaic integration options for roof-mounted solar arrays
• Rainwater recovery systems for apron drainage and non-potable use
• Climate-control compatibility for constant-temperature and humidity environments

Because these systems are routed through the structure during design, you avoid the field-drilled penetrations and load-path compromises that come with post-construction retrofit.

Lifecycle Cost Advantage

Steel vs. Concrete: 35% Lower Total Cost of Ownership

• Faster fabrication and assembly (steel ships in weeks, concrete cures in months)
• Lighter foundation loads reduce substructure costs
• Modular end-wall design allows future bay expansion without disturbing the original structure
• 30-year service life with lower maintenance than concrete or fabric alternatives

Core Application

• Commercial wide-body parking and MRO facilities
• Military tactical and strategic transport shelters
• Cargo and logistics air hubs
• Emergency response and command centers

The full lifecycle cost of a steel aircraft hangar is 35% lower than that of a concrete solution, making it suitable for civil aviation maintenance bases, military airports, and large-scale commercial fleet operations.

Beyond heavy‑duty custom‑built aircraft hangars, this steel frame solution can also be delivered as factory‑prefabricated kits for faster deployment.
